Aurora, Colorado Police Chief Dan Oates has confirmed reports that investigators in the Batman Massacre found a 100-round drum-style rifle magazine at the scene of the crime. Even before the discovery, Sen. Frank Lautenberg’s (D-N.J.) office announced plans to reintroduce legislation restricting rifle magazine capacity. “If reports are correct and a high-capacity gun magazine was used to commit these awful murders, Senator Lautenberg will absolutely renew his effort to limit the availability of this dangerous firearm attachment,” Lautenberg’s PR guy told The Huffington Post. “Lautenberg, one of the most vocal gun control advocates in the Senate, introduced a bill to limit high-capacity magazines following the shooting of former congresswoman Gabrielle Giffords . . . The bill went nowhere.” With a bit of luck, this one will follow it. Still, watch this space.
